Organic Sessions To-Date vs Month to Month[ Edited ]
November 2016 - last edited November 2016
I am comparing organic sessions by country for the current year (2016) and when the entire date range is selected from Jan 2016-Oct 2016 it gives me a completely different total than the month-to-month totals tallied up. There's actually a 3,420 session discrepancy that I'm totally lost on.
Why is there such a difference in these reports? Which one is the more accurate depiction of organic sessions by country?

How many sessions are we talking about here? If you're using the free version of GA, looking at 2 dimensions together such as Medium and Country will cause Google to sample your data if sessions are above 500K. I believe the default sampling is set to around 250K sessions but you can use to slider to increase to about 500K.
